155,420. Divided and this application filed February 13, 1920. Serial No. 358,480.

To LZZ 2li/om t may concern Be it known that l, @Hannes J. Lin'rz, a citizen of the VUnited States, and a resident of the city of Newark, in the county of llssex and State of New Jersey, have invented certain new and useful improvements in a lteceiving and 'llransferlillechanism for ll'rapping-lllachiiies5 and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon which forni a part of this specification.

rllhis application constitutes a division of my co-pending application for patent for wrapping machine filed March 17, 191'4, eria No. 155,420.

in the wrapping machine forming the subject matter of my application for patent above referred to the wrapped articles (in the present instance caramels) are ejected from a vertical revoluble carrier wheel downwardly against spring-thrust receiving means for holding the wrapped article against the periphery of the wheel and sub: sequently serve to advance the same toward discharge, causing the wrapped article to pass into and between resiliently acting lconining members which holdthe folds of the wrapper closely to the article until actual discharge. n

It is an object of this invention, therefore, to provide a receiving and transfer mechanism for the wrapped articles which receives the articles directly from the carrier wheel and thereafter effects transfer thereof along a chute toward dischargewith a step by step movement. Each additional article discharged from the carrier wheel receives an impulse to thrust the same into the chute and thereby effect movement of all of the articles therein.

@ther and further important objects .of this invention will be apparent from the disclosures in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

parts Description.

The frame structure of the wrapping machine shown fragmentarily in F ig. 5 is indicated as a whole by the reference numeral l and the front plate attached thereover shown in Figs. l, 2 and 5 and forming part of the frame is denoted by the reference numeral 2. Journaled within a boss 3 on the plate 2 is a shaft t provided with a gear 5 on its inner end driven by a gear 6 forming a part of the power mechanism of the wragr ping machine. @n the other end of the shaft 4.- a crank is secured to rotate with aid shaft, and has connected thereto a link 8. Said link S is pivotally connected to the upper end of a crank 9 which is journaled upon a casing l0 'secured over the frame plate 2. Pivoted adjacent to said crank 9 is another lever or crank il and said levers are connected to one another at theiiI upper ends by a link l2 which is operated thereby. The forward end of said link l2 is formed with a pusher plate or ejecting head 13 aud said head extends outwardly on each side of and is adapted to slide upon the upper surface of two similar levers la during certain portions of its movement. rlhe arms or levers 14; are in reality the extended ends of a forked lever, that is, they are integrally co|inected with one another at their point of pivotal connection as clearly shown in Fig. 5 and are mounted upon a pintle 15. Said pintle shaft is supported in bearing blocks 16 which are integral with one another and attached upon a portion of the casing 10 by screw bolts 17 shown 'in Fig. 5. Each of Vsaid levers 14 has a straight flat portion 1S and at the end thereof is cut away to form a toothY 19, as shown in Figs. 3 and 7. Said forked leveis 14 are normally supported and thrust upwardly by a coiled spring 20 which as shown in Fig. 7 rests upon a stud 21 on the top casing 10 and engages around another stud forked levers 14. Said spring 2O acts to hold said levers 14 upwardly in pressure relation against the under side of the carrier wheel 23 by which the articles 24 are carried during the application of a wrapper thereon.' A bracket 25 shown in Figs. land 2 is attached by means of a stud 26 upon the frame plate 2 and rigidly securedupon said bracket is a channel-shaped guide 27 the side walls of which extend beyond the end thereof and are iiared outwardly as denoted by thereference numeral 28 and shown in l? ig. 4. At its other end said side walls eX- teiid beyond the bottom thereof as shown in Fig. 3 and securel on the bottoni of said 'channel' at the discharge end thereof by v so that the fiat' portions means of a rivet 29 or other suitable means is a. false bottom 30 whiclnas shown in Fig. 3, duc to its inherent resiliency is normally sprung upwardly and at its free end is provided with a tooth extension 31 adapted to be engaged by the toothed ends 19 of theA levers 14 when the same are forced downwardly by an article 24 received from the wheel 23 into the relation shown in Fig. 8 18 of the levers 14 are flush with said false bottom 30. A. stud 32 secured upon the front of the wrapping machine structure projects outwardly there-- .from andhas attached thereon ra long, re-

silient confining bar 33 which is normally impelledvtoward the false bottom 30, and a series of articles 24 leaving the machine are forced therealong in the channel 27 and held tightly between. said bar 33 and the false bottom 30 so aste fix the creases in the folds of the wrapper on the articles.

Operation.

llhen an article has had its wrapper completely folded thereon while in the carrier wheel 23 and is ejected from the carrier pocket in said wheel, it is first forced against the forked levers 14, as it leaves the carrier wheel, which are pressed downwardly against the compression of the spring 2O thereby preventing accidental displacement of the article during` its ejectment from the wheel. As the carrier wheel' continues its movement-,the smooth periphery thereof beyond the pocket bears upon the top surface of the .article'24 as shown in Figs. 1 and 8, thereby holding the arms 14 downwardly.

22 on the under side of theV 'riphery ofthe carrier .wheel 23,`

The next operation to take place before ani other article is discharged is transfer of the article into the chute or channel 27 by the pusher plate or head 13. The operation of the respective cranks 9and 11 carrying the' link 12 on which the pusher head 13 is mounted is timed so that the pusher head is impelled forwardly against the larticle 24 striking the same and moving kthe article along on the levers 14 from the position in Fig. 1 to a position withinY the chute on the false bottom 30 shown in Figs. 2 and 3.l lmmediately thereafter the pusher head 13 is retracted byv return movement of the link or bar 12, and retraction of the pusher head 13 from over the flat portions 1S of the levers 14 permits said levers to be impelled upwardly again into contact with the lpe- As succeeding articles 24 are discharged from the carrier wheelandY thrust into the discharge chute on channel 27, to form a .series as shown in Fig. 3, the entire series is Vgiven an intermittent advance by the .addition from'time to time of an article ejected from the carrier wheel. As said articles, as shown in llig. 3, pass through'the discharge chute beneath the resilient bar and supported by the resilient false bottom 30, thefolds in the wrapper arecreaserhand since the final 95 folds ofthe wrapper are on the .top surface of an article in the discharge chute, the creasing thereof insures retaining of the wrapper upon the article. Y y

.I am aware that numerous det-ails of con- 10o structionk may be varied Ythrough a wide iban without departing from the principles Y of Yhis invention, and l therefore do not purpose limiting` the patent granted otherwise than necessitated by the prior art.
